New techniques help prevent radiation from being harmful to astronauts

A new Chinese software program capable of calculating radiation outside the space has protected astronauts from radioactive contamination in the country's second-person mission.

Liu was also the one who led a research team responsible for forecasting the space environment for Shenzhou ship flights over the years.

At a space-saving scientific conference in Beijing yesterday, Liu said China's future space program will increase the number of times going out into space. This poses more challenges for professionals in ensuring the safety of astronauts.

Based on radiation research both at home and abroad, Chinese scientists have developed a software that measures the level of radiation that astronauts suffer during space flights.

'In the Shenzhou V and VI missions, researchers used this software to calculate and monitor the level of radiation affecting astronauts,' Liu said. 'If the radiation exceeds the safety level, the ground operator will contact the astronaut to show how to deal with radiation and protect astronauts.'

High-energy radiation is a major threat to the safety of astronauts in the universe. It can be harmful to astronauts' cells, tissues, organs.
